Painting Lower Unit.
 

Working through the light rain here taking off all that old Merc. paint that is all cracked. Have Merc. paint, but wondering if a normal automotive primer will be fine. ???

hamster, i would try to locate a high-zinc primer.

Re: Painting Lower Unit.
 

Was hoping to use just some auto primer, I know if I go to West Marine, a can of primer is tripled in price. :(

Re: Painting Lower Unit.
 

probably wont be so bad if its not left in water.
i think that applies more to boats left in the water.

Re: Painting Lower Unit.
 

Hammer's painting again??? Yea, experimenting with paint compatability is a great idea!

Re: Painting Lower Unit.
 

I agree w/ CTT's 1st suggestion about the hi-zinc primer...spend a little more now and ya won't have to do it again next year ;) ...


Are there screens inside the intake vents?...make sure those don't clog up w paint...matter of fact, I'd tape each screen B4 painting...and I AIN'T kiddin' about that ;) ...

Re: Painting Lower Unit.
 

Pikfish, yes, painting again >:(, but spray painting. Brings back memories of my juvenile days. ;D
Heavy down pour, no more work for now.
Thanks REEL, I'll cover those vents up with tape.
Just off the phone with West Marine, they carry a high zinc primer. 16 bucks a can. Guess that isnt to bad.

Hammer,

I am painting my engine also. Any areas that are down to bare aluminum need to be primed with a self etching primer such as zinc chromate. (yellow/green) I just bought a grey self etching primer for aluminum at a auto paint store which was only about $8.00 a can. If you use the zinc chromate, you only put down a very light coat for best results. If you don't use a self etching primer your paint will not stick properly and you will be painting again shortly. I hope this helps!

Hammer:

Take Geekie1 advice. Zinc chroamtic is a pain to shoot with a spray gun and you won't be happy with the finish if its applied wrong. Although I have had better luck with pre-package spray cans, I can never get it to shoot from a gun without "stringing up" on me and making a big mess - immediatley followed by lots of sanding.

Given the price and the difficulties of spraying it, I don't think its worth it on a engine that will be trailered. Use a automotive self etching primer and you'll be fine.

Re: Painting Lower Unit.
 

Hammer the picture on the can sells me ... you got the rite stuff ,,,, paint away brother ;D ;D ;D

Re: Painting Lower Unit.

Re: Painting Lower Unit.
 

One other suggestion, if you haven't planned on it yet; use a good grease & wax remover just before you paint. Get lots of clean rags and wipe it all down to get rid of anything left from the cleaning/sanding process. My outdrive is pretty nasty looking. I may takcle this one after my wiring job. Good luck.

Re: Painting Lower Unit.
 

AZ has some good stuff called metal prep for just that!!

Re: Painting Lower Unit.
 

off Monday and Tuesday, so hopefully I'll getter done. Thats if it doesnt rain. ;D

Re: Painting Lower Unit.
 

Well I painted teh lower unit and not happy with it at all. It does look better than all that cracked paint. But I wish I could have stripped all the paint down. I used the Zinc primer then two additional thick coats of primer and you could see where the old paint is and the grinding marks all. Well, I like I said. I HATE PAINTING !!

Well, if we ever get 10 ft. snow drifts in Lewes, you will never be able to see it.

Guess I'll be repainting it next year. Then maybe I'll have time to strip it all down.

Re: Painting Lower Unit.
 

See you can't see any of those flaws in the paint what so ever.

Re: Painting Lower Unit.
 

Great job Hammer!!...I think yer gonna be amazed at how long that'll last ;) ...

Re: Painting Lower Unit.
 

I told you to leave it alone!! ;)

Who cares what it looks like, you only see the top in the water anyway!! and fish don't care!!

Mine looks worse then that!! I could careless!! It runs!

Re: Painting Lower Unit.
 

Thanks guys. ;)

Re: Painting Lower Unit.
 

Looks good. ;) ;)

Maybe you should have left it orange,
the flaws don't show as much. :-X

Re: Painting Lower Unit.
 

Well, I went ahead and painted up the engine cover. Wish I had some new decals to go along with it.
It looks great with the green and yellow polin mixed in with the paint *>:(
I was waiting on the sand storm next to roll on through while painting. I hate Painting !!
